“We’ll need to examine the amendment in closer detail before we can comment on any specific project, but the opportunity to deploy an improved technology could help a project improve its energy yield and profitability, which boosts the business case at a time when other headwinds, like ongoing uncertainty about energy policy, have stalled further investment in wind farms in Australia.”

Green groups have accused the government of double standards over the laws, saying some planned wind farms were unfairly locked into older technology, while newer ones could race ahead with the latest improvements.

“Minister Guy’s decision to amend part of the government’s wind farm planning laws is welcome, but more reform is needed to create jobs in the sector,” Friends of the Earth renewable energy spokesperson Leigh Ewbank said.

In April, Friends of the Earth claimed $864 million worth of projects had been scrapped in Victoria because of the state’s planning laws.

A spokeswoman for Mr Guy said the changes would only affect technology and would not apply a to a two-kilometre setback zone between turbines and homes.
